HYDRAULIC MOTOR FOR VESSELS.

SPECIFICATION forming part of Letters Patent No. 286,477, dated October9, 1883.

Application filed January 26, 1583. (No model.)

To all whom it may concern.- Be it known that I, SIMON OBRIEN, ofBristol, in the county of Bristol and State of Rhode Island, haveinvented a new and Improved Motor, of which the following is a full,

clear, and exact description.

The object of my invention is to provide a new and improved motor formarine vessels, in which the steam is applied in the most direct way andwith very little machinery.

The invention consists in a motor formed of a series of pipes and a cockso connected that water can be drawn in at the bottom of the vessel andforced out at the rear end of the same, whereby the vessel will be movedforward, or water can be drawn in at the rear end of the vessel. andforced out at the bottom of the same toward the front end, whereby thevessel will be moved backward.

The invention also consists in attaching a hose or flexible'pipe to theend of the pipe projecting from the stern, and also attaching the saidhose to the rudder, whereby the water issuing from the said hose willassist in stter- 2 5 ing the vessel. Reference is to be had to theaccompanying drawings, forming a part of this specification, in whichsimilar letters of reference indicate corresponding parts in all thefigures.

Fig. 2.

A steam-supply pipe, A, connected with a boiler, B, or with a pipeleading to a boiler,.

is coupled at its outer end to the casing O of a three-way cock, D, towhichcasing is at-- o tached, at one end, a curved pipe, E, leading intothe top of a union-piece, F, that part of the pipe E projecting into theunion-piece being contracted. To the other end of the casing G a curvedpipe, G, is attached, the

5 outer end of which is attached to and projects into the front end ofthe union-piece F, the proj ecting end of the pipe G being alsocontracted.

To the bottom of the union-piece F a pipe, H, is connected, whicheiztends through the bottom of the vessel and projects toward the frontend or bow of the same.

To the rear end of the union-piece F a pipe, J, is coupled, whichextends to the stern of the vessel and projects from the same.

To the outer end of the pipe J a flexible pipe or hose, K, is coupled,which is attached to the rudder L. If desired, the said flexible "pipeor hose K can be dispensed with. If the through the pipe 3 and out atthe rear end of the same at the stern of the vessel. If the vessel is togo straight forward, the rudder is held straight, and the stream ofwater will be projected from the pipe J in a line parallel to the lineof the length of the vessel; but if the vessel is to be turned to oneside,the rudder is turned -correspondingly, and the stream of Water fromthe pipe J will issue from the end of the same at an angle to the lineof the length of the vessel, and thus will assist in tu rning thevessel. If the vessel is to be moved backward, the three-way cock D isso adjusted that the steam cannot pass from the pipe A through the cockto the pipe G, but passes from the pipe A through the cock D and throughthe pipe 1 and is ejected from the contracted end of the samedownwa-rdinto the union F and pipe H, thus causing a suction of 8 5 the waterthrough the pipe J, which water passes into the union F and is forcedout of the same through the pipe H, the water ejected from the end ofthe pipe H forcing the vessel backward.

By means of my improved motor the complicated machinery used heretoforecan be dispensed with. There is but very little wear and tear, and nogrease, oil, packing,&c., are required, and as the steam is applieddirectly 95 there is no great loss by friction, &c., as in othermachinery.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. In a motor, the combination, with thesteanrsupply pipe A, of the three-way cock D,

the pipe E, extending into the top of the unionpiece F, the pipe G,extending into the front end of the same, the pipe H, coupled to thebottom of the union and extending to and projecting from the bottom ofthe vessel toward the front end of the same, and of the pipe J attachedto the rear end of the unionpiece and extending to thestern of thevessel, substantially as herein shown and described, and for the purposeset forth.

2. In a motor, the combination, with a Vessel, of the pipe J, extendingto the stern of the vessel, and through which pipe water can be ejected,of the flexible pipe or hose K, attached to the end of the pipe J, andattached to the rudder L, substantially as herein shown and described,and for the purpose set forth.

3. In a motor, the combination, with the escAw boiler B, of the pipe A,the three-way cock D, the pipe E,proj ecting into the top of theunionpiece F, the pipe G, projecting into the front endof theunion-piece, the pipe H, coupled to the bottom of the union-piece andprojecting from the bottom of the vesseltoward the front end of thesame, the pipe J, coupled to the rear end of the union-piece andextending to the stern of the vessel, and of the flexible pipe or hoseK, attached to the end of the pipe J, and of the rudder L, substantiallyas herein shown and described, and for the purpose set forth.
